When supernova explode , they fling petrol out into space , creating beautiful , gauzy remainder for us to slaver over . Supernova remnant G352 is pretty , but weird . It ’s accumulate extra stuff , misplace its neutron virtuoso , and looks dramatically different count on the wavelength .
The strange remnant is located about 24,000 light-colored years from Earth , in the direction of Scorpius . The field of vista in this complex is 14.5 arcminutes across , or about 1,000 light-headed - twelvemonth wide . It ’s a multi - spectral composite with each colour share coming from a different wavelength record by a different telescope .
Blue is x - rays , white is visible light , orange is infrared light , and pink is radio waves . X - ray are trance by NASA ’s Chandra X - shaft Observatory . Optical data are from the Digitized Sky Survey . Infrared wavelength are from the Spitzer Space Telescope , and finally , radio wave are photographed by the National Science Foundation ’s Karl G. Jansky Very Large Array .
So , how is this not - so - little pretty oddment so strange ?
To lead off with , it appears that G352 is extremely esurient . The end has amass most 1032 kilograms of material — 45 times the mass of our sun . While all supernova remnants swing out up some extra material as they flourish , that ’s a whole lot more than normal .
Not only that , but those cooler remnants are n’t producing nigh as many X - rays as the hotter blowup debris . Most of the utter X - re are hot ( 30 million degrees Celsius ) , not cooler ( 2 million grade Celsius ) , suggesting that most of the 10 - rays are being produce by the explosion debris , and not the material span up in the intervening time . This would make sense for a sister supernova , but G352 is 2,200 years old , and should have transition by now .
Next , check out G352 in unlike wavelengths . intermit the composite aside , that ’s X - rays ( naughty ) in the top left , with seeable lightness ( white ) in the top right wing . move to the bottom row , the bottom pass on is infrared ( orange ) , and bottom right is tuner wave ( pink ) .
The leftover is nice and undimmed in X - re — that ’s normal . It ’s almost non - real in visible light ; again , awesome . The globs of infrared off to the sides are not directly related to the supernova , so we can disregard them . The radio wave is where things get strange : why is the remnant an infilled ellipse in X - ray , but only the forbidden rings glowing in tuner ? Just what sort of evolutionary path is this remnant headed down , and what will it expect like in the futurity ?
Finally , a supernova this big should have left behind a neutron star , but we are n’t finding it . possibly it produced a light neutron maven , so feeble we have n’t discover it yet . Or , more exotically , perhaps the supernova produced a ignominious hole instead .
Overall , this is a whole mickle of weird going on for one explosion . you may read more about how this organisation is shaping up to be downright unusual , and some speculation for what ’s pass away on , inXMM - Newton and Chandra Observations of the Ejecta - Dominated Mixed - Morphology Galactic Supernova Remnant G352.7 - 0.1
